Experimet #2 Chemical Proportionality Carbonate and Hydrochloric Acid* Experiment by: Jaimin Patel, Heba A. Introduction: Basic principals, such as the making of cement and the use of baking soda, of chemistry were used earlier than the 19 th century. In doing this experiment, there is one implicit rule: we consdier how much by considering the relative preportions. The objective of this lab is to observe and measrure the change in molality and how it affects the amount of. We will also add an acid base indecator when that will dramatically change color when the reaction is complete. We use a chemical method to determine the concentration. The formula for this experiment is: M 2 CO 3 (s) + 2HCl (aq) 2MCl (aq) +CO 2 +H 2 O (l) Procedure: Step I 1. Gather all ingrediants 2. Get <60 mL of 0.25M concentrated solution of Hydrochloric Acid (HCl) in a beaker. 3. Get a watchglass and add the Sodium Carbonate (Na 2 CO 3 ). Measure the mass of the watchglass with the Sodium Carbonate. 4. Get a smaller beaker and added 15 mL of HCl solution in the smaller beaker. To be accurate with the 15 mL use a graduated cylinder.
